Abstract
1532414 Chord indicators G A COURNOYER 21 Nov 1975 [9 Dec 1974] 47939/75 Heading G5X A ruler 3 marked with a chromatic scale is slidable in a groove 2 in a base plate 1 which is marked with a diatonic scale 4 adjacent ruler 3 and with chord indicators each of which includes pointers 8 of distinctive notes of the corresponding chord and located at the specific degrees 6 of the ends of the component thirds of the chord, each component third being distinctively coded, e.g. by colour, to denote its qualification, e.g. diminished, augmented, major or minor. Further marks 13 may be associated with each chord indicator to identify the name and qualification of the chord. A diatonic scale 4, 5 and a set of chord indicators may be provided on opposite sides of the chromatic scale ruler 3 for major and direct minor chords. In a second embodiment, Fig. 2 (not shown) for indicating tonal chords or their derivatives, an additional pointer (14) is positioned along each indicator to identify the corresponding modal note of that cord. Tonal chords may also be identified.
